Back in the days before Apollo, no one knew about the dangers of traveling outside of the protective electro-magnetic field or how one CME could have completely ended the mission and the astronauts' lives. I never said they were totally ignorant, but cosmic radiation and solar activity are huge...

:smile: So is there any explanation about this "sun goes dark" claim? I can't even see what they mean in the videos. To me, it looks like either photoshop work or a computer glitch.

I understand now. Still, I guess we need to be a little reckless in order to learn.

I agree that probes should definitely come first; however, we can't hold off forever on a manned mission to Mars. Some of the techniques we learn for space travel are learned on the actual missions. If we look at the event with Alexei Leonov, that is how we learned that space suits needed to be...

It happens every day? Are there any resources that say this? I would love to see them.

Thank you for the links and the information. I appreciate it tremendously!

To actually return to the topic at hand, I believe there are a few problems that need to be resolved before a space elevator can come to be. The space elevator is dependent on a very long cable, one side connected to Earth and one side connected to a station in orbit. This tether would have to...

Thanks! That is some interesting information. If Venus does not have tectonics, then what drives the volcanic activity?

About how quickly would it have to rotate to produce appreciable gravity? OK, that is good to know. Wow, I never even thought of that aspect. An EM field would have repercussions on the computer equipment on the spacecraft . So the problem is to find a material that can protect from...

I see what you mean. Hindsight is 20/20. Yes, that is correct. I am judging by today's standards. Even if we were to turn back the clock, I still think it was a little reckless. Our goals should not have been to "beat the Russians" to the moon. In that haste, we might have overlooked...

I understand what you are saying, and I do not regret the Apollo missions at all. My point was that the dangers of that mission were not known. Imagine if there had been a CME (directed towards Earth) while the astronauts were on the moon or on their way to the moon. They would have died...

I know there are many obstacles in the way of sending a manned mission to Mars, as described by Chronos in the "High School Debate" thread. I have a few questions of my own about ideas that will help to overcome these obstacles. 1. The weightlessness is one of the big barriers. I have seen...

OK, then if the sun will begin to lose mass once it enters the red giant phase, doesn't it stand to reason that the gravitational pull on Earth will decrease?

I'm sure you can use Wiki as a reference, as long as you confirm the information with another source. The only reason Wiki is unreliable is because anyone can edit the information. I have checked some of the references that Wiki lists and found dead links. If you do use it, just confirm your...
